Canada takes final steps to ban Asbestos

by Paul Manning, Manning Environmental Law

Environment and Climate Change Canada, along with Health Canada, published the Prohibition of Asbestos and Products Containing Asbestos Regulations in the Canada Gazette, Part II on October 17, 2018.

These new regulations apply to any person who manufactures, imports, sells or uses asbestos or products containing asbestos.

The regulations prohibit the import, sale and use of all forms of asbestos as well as the manufacture, import, sale and use of products containing asbestos, with a limited number of exclusions:

  • ongoing exclusions for
    • the transfer of physical possession or control of asbestos or a product containing asbestos to allow its disposal
    • the re-use of asbestos in existing road infrastructure into new road infrastructure or in asbestos mining site restoration
    • the import, sale or use of military equipment serviced overseas with a product containing asbestos if there were no technically or economically feasible asbestos-free alternatives available
    • the import, sale or use of asbestos and products containing asbestos for display in a museum or for use in a laboratory
  • exclusions until
    • December 31, 2022 for the import, sale or use of products containing asbestos to service equipment in nuclear facilities, or to service military equipment, if there are no technically or economically feasible asbestos-free alternatives available,
    • December 31, 2029 for the import and use of asbestos for chlor-alkali facilities using asbestos diaphragm technology

The regulations include:

  • permit provisions for unforeseen circumstances where asbestos or a product containing asbestos is used to protect human health or the environment, if there is no technically or economically feasible asbestos-free alternative available
  • permit provisions for the import and use of products containing asbestos to service military equipment and equipment in a nuclear facility, if there is no technically or economically feasible asbestos-free alternative available
  • provisions requiring the submission of reports from museums, laboratories, and military, nuclear and chlor-alkali facilities, as well as permit holders, who import, use or display asbestos or products containing asbestos. The preparation and implementation of an asbestos management plan is also required in most cases

The regulations do not apply to:

  • asbestos integrated into a structure or infrastructure before the day on which the Regulations come into force (such as asbestos integrated into buildings and civil engineering works), or to products containing asbestos used before the day on which the regulations come into force (such as equipment installed in a facility, vehicles, ships, and airplanes)
  • asbestos and products containing asbestos in transit through Canada
  • mining residues, except for certain high risk activities which are prohibited, including:
  • the sale of asbestos mining residues for use in construction and landscaping activities, unless authorized by the province, and
  • the use of asbestos mining residues to manufacture a product that contains asbestos

In addition to these regulations, the existing Export of Substances on the Export Control List Regulations (ESECLR) and Schedule 3 to the Canadian Environmental Protection Act, 1999 were amended to prohibit exports of asbestos, with a limited number of exceptions.  These provisions ensure that Canada continues to meet its export obligations under international conventions, including the Rotterdam Convention. The regulations and related amendments to the ESECLR come into force on December 30, 2018.

Financing Soil Remediation: Exploring the use of financing instruments to blend public and private capital

The International Institute for Sustainable Development (IISD) recently released a report entitled Financing Soil Remediation: Exploring the use of financing instruments to blend public and private capital.

The report makes the statement that governments around the world are looking at opportunities to attract private capital participation in both land remediation and its productive use and redevelopment thereafter. The business case is intrinsically the value capture in the increase in retail price of land and related business opportunities once the remediation is complete. However, where land value capture is lower and related revenue streams remain uncertain, the case for private capital participation is much less compelling. Governments, in this case, have to fund the remediation through public budgets and thereafter seek opportunities to partner with private counter-parties to use the land as “fit for purpose.”

The IISD report presents 17 case studies on a variety of financing instruments that blend public and private capital. Each case study includes a short discussion on the extent to which each instrument could be used to finance the remediation of contaminated soil.  The case studies in thereport demonstrate a variety of financing strategies, from index-linked bonds to savings accounts and from peer-to-peer lending platforms to debt-for-nature swaps.

This report is a part of a series of outputs of a four-year project, Financing Models for Soil Remediation. The overall objective of the project is to harness the full range of green finance approaches and vehicles to manage the associated risk and fund the remediation of contaminated soils.

The series of reports focuses on the financial vehicles available to attract investment to environmental rehabilitation of degraded land and the financial reforms needed to make these vehicles a viable and desirable means of investing in land rehabilitation. The IISD draws on best practices worldwide in funding environmental rehabilitation, with a special focus on the design and use of financial mechanisms to attract private investors, share the risk and offer a clear benefit for the rehabilitated land.

Several lessons emerge from these case studies described in the report in the context of financing the remediation of contaminated land, including the following:

  1. As with all financial arrangements, the risk appetite of different investors has to match the risk profile of
    the investment. It is difficult to crowd in private and institutional investors when projects remain below
    investment grade.
  2. Money follows a good deal. When legal, technological, revenue and other risks are understood and are
    transparent, feasible ways to reduce these uncertainties can be planned and financing strategies can be
    worked upon.
  3. When there is reasonable certainty that the value of the land will increase after remediation and will
    subsequently generate stable and predictable revenues, there is a strong case for blending public and
    private financing.
  4. When, on the other hand, projects have less attractive revenue potential, governments have to step in to
    finance the remediation, or at least a larger part of it.

Kitchener, Ontario’s Largest Brownfield Redevelopment

Kitchener, Ontario’s biggest abandoned industrial site is well on its way into being redeveloped into a 50,000-square-foot facility for a tool and die company and a 3,150-square-metre medical office building.

The 78-acres industrial site is located on the southeast corner of Bleams Road and Homer Watson Boulevard in Kitchener, approximately 100 km west of Toronto.  It was developed with a 1.2 million square foot manufacturing facility that was constructed in several phases beginning in 1967.  The facility had been used by Budd Canada to manufacture auto parts, ThyssenKrupp Budd Canada, and eventually by Kitchener Frame.  The land has sat idle since 2009.

In 2010, a group of investors purchased the property with the vision of redeveloping it.  It has taken eight years for the redevelopment to reach its current state – a series of approvals from various levels of government and a plan to start construction in early 2019.

The site is still waiting approval of the Record of Site Condition (RSC) from the Ontario Ministry of the Environment, Conservation and Parks (MOECP). It was filed in January of 2018.  An RSC is typically required by on Ontario Municipality if a property is being redevelopment for a more sensitive land use (i.e., from industrial to commercial or residential).  It is filed by an environmental consultant following the clean-up of a property.  It summarizes the environmental condition of a property based on the completion of environmental site assessments (i.e., Phase I & II ESAs).

Site Clean-up

Demolition work and subsequent site cleanup got underway in November 2011. The environmental remediation cost an estimated $8.5 million.

A soil remediation program was conducted at the property between April and June 2016 in an attempt to reduce the
concentrations of the contaminants of concern s in soil identified at the property. The remediation activity at the site included the excavation of approximately 9,360 cubic metres (5,200 tonnes) of contaminated soil for disposal at a licensed non-hazardous waste landfill.  No sediment or groundwater was remediated or removed for the purpose of remediation.

The clean-up of the site included the preparation of a Streamlined Tier 3 Risk Assessment Report.   A risk assessment provides an approach for developing property specific standards (PSS) under Ontario Regulation 153/04 (Records of Site Condition (RSC) – Part XV.1 of the Act), made under the Environmental Protection Act (the Regulation). A Tier 3 Risk Assessment goes beyond the generic approach of a Tier 2 risk assessment and involves a longer and more detailed review by the MOECP. According to the filed RSC, the MOECP has approved of the Streamlined Tier 3 Risk Assessment.

As reported in the Kitchener Post, a total of $7,787,000 in direct remediation costs are eligible to be reimbursed by the city and region under a joint tax increment grant application. The total estimated post redevelopment assessment value is estimated at more than $111 million.

Redevelopment

In an interview with the Daily Commercial News, Janinen Oosterveld, manager of site development and customer service in Kitchener-Waterloo’s planning division stated: “Approvals to finalize the subdivision of the lands into development parcels is currently underway.”

As of mid-October, the city had received site plan applications for two developments — a 50,000-square-foot facility for a tool and die company and a 3,150-square-metre medical office building.

Plans for the redevelopment envisage nine industrial parcels, totaling approximately 39 acres.

When Oil and Water Mix: Understanding the Environmental Impacts of Fracking

Dan Soeder, director of the Energy Resources Initiative  at the South Dakota School of Mines & Technology, has co-authored the cover article titled “When oil and water mix: Understanding the environmental impacts of shale development,” in the recent issue of GSA Today, a magazine published by the Geological Society of America.

The article explores what is known and not known about the environmental risks of fracking with the intent of fostering informed discussions within the geoscience community on the topic of hydraulic fracturing, says Soeder. Soeder’s co-author is Douglas B. Kent of the United States Geological Survey.

In this paper, Soeder and Kent bridge the gap in consensus regarding fracking, providing current information about the environmental impacts of shale development. The article is open access and adheres to science and policy, presenting a complicated and controversial topic in a manner more easily understood by the lay person.

“Geoscientists from dinosaur experts to the people studying the surface of Mars are often asked by the public to weigh-in with their opinions on fracking. We wanted the broader geoscience community to be aware of what is known and not known about the impacts of this technology on air, water, ecosystems and human health.  A great deal has been learned in the past decade, but there are still critical unknowns where we don’t yet have answers,” Soeder says.

Development of shale gas and tight oil, or unconventional oil and gas (UOG), has dramatically increased domestic energy production in the United States and Canada.  UOG resources are typically developed through the use of hydraulic fracturing, which creates high-permeability flow paths into large volumes of tight rocks to provide a means for hydrocarbons to move to a wellbore. This process uses significant volumes of water, sand, and chemicals, raising concerns about risks to the environment and to human health.

In the article, Soeder and Kent address the various potential impacts of fracking and how those impacts are being addressed.  Risks to air include releases of methane, carbon dioxide, volatile organic compounds, and particulate matter. Water-resource risks include excessive withdrawals, stray gas in drinking-water aquifers, and surface spills of fluids or chemicals. Landscapes can be significantly altered by the infrastructure installed to support large drilling platforms and associated equipment. Exposure routes, fate and transport, and toxicology of chemicals used in the hydraulic fracturing process are poorly understood, as are the potential effects on terrestrial and aquatic ecosystems and human health.

Brantford Showcases its Brownfield Projects

Known as the Telephone City, Brantford may also become famous as one of the first municipalities in Canada to proudly showcase its brownfield projects.

Instead of hiding from its industrial past, the city is showcasing several brownfield projects and is encouraging residents and visitors to take the self-guided tour.  Eight projects in various stages of remediation or redevelopment are highlighted in the  tour.

Highlights of the the tour are the Greenwich Mohawk Site, Sydenham-Pear Site and Edward Gould Park.  The Greenwich Mohawk Site alone is over 50 acres and was remediated over the course of two years, starting in 2014.

 

 

 

The City is investing $5,000 per year to promote the tour and hopes to attract interested individuals, school groups, and others.  The tour itself provides participants with access to historical photos, newspaper articles and other project details through the tour website.

Users can access the Brownfields Discovery Tour online at Brantford.ca/BrownfieldsTour where they can follow along digitally or print a hard copy of the tour.

“The City of Brantford has become widely recognized as a leader for remediation, redevelopment and public education of brownfields,” said Amy Meloch, chair of the brownfields community advisory committee in an interview with the Brantford Expositor. “The tour is an exciting continuation of the work of the committee to raise awareness to both residents and visitors of the extensive work already accomplished in the city.”

The sites on the tour include those that are municipally and privately owned.  They are:

  • 186 Pearl St. – a 0.38-hectare site located in a residential area, this site was home to Brantford Emery Wheel Co. (1910-1920) and the Brantford Grinding Wheel Co. (1920-1939). Bay State Abrasives was involved in similar manufacturing operations there. The city removed an underground storage tank, removed the existing structures, cleaned the contaminated soil and planted sod at a cost of about $175,000. The property has been converted into a park.
  • 347 Greenwich St. and 22 and 66 Mohawk St. – Referred to collectively as the Greenwich Mohawk Brownfield Site, the companies and industry formerly housed on these properties are a significant part of the city’s history. The 27.9-acre 347 Greenwich property is the former site of Massey-Harris Co., established in 1891. It employed thousands of Brantford employees over the years. A 2005 fire destroyed most of the buildings and the city acquired the property in 2007.
  • 22 Mohawk St. – This 7.25-acre property has been home to Adam’s Wagon Co. and Brantford Coach and Body, later Canada Coach and Body, where military vehicles were manufactured during the Second World War. Later, Sternson Group was there.
  • 66 Mohawk St – The Brantford Plow Works, later Cockshutt Plow Co., was established here in 1877, making high-quality farm implements. The farm division was sold to White Farm Equipment in 1962. That company went bankrupt in 1985. The city acquired all three properties by 2007 and a two-year remediation started in 2014 at a cost of $40.5 million.
  • Sydenham Pearl site – Consists of two properties: 17 Sydenham St., the former Crown Electric, and 22 Sydenham, the former Domtar (Northern Globe) site. The sites served as the main locations for mass industry for almost a century. The city took over the properties 2004 and 2006. Remediation was done in 2015 and 2016 and a soil cap was installed. The site will be green space until next steps are explored by the city.
  • 85 Morrell St. – The city sold the property, once occupied by Harding Carpets Limited, to King and Benton Development Corporation, which cleaned and renovated the 10-acre property to include warehouses and offices for industrial use.
  • 168 Colborne St. West – This 11.5-acre property was the site of the former Stelco Fastners manufacturing plant. In 1999, it was purchased by King and Benton. Work is underway to redevelop the site for mixed uses, including multi-storey residential buildings.
  • 111 Sherwood St. – Home to Brantford Cordage Co. during the early 1900s. At its peak, the twine producer employed 700. It has remained active with a variety of commercial and industrial uses, including a brewery and fitness studio.
  • 232-254 Grand River Ave. – In 1891, this 4.87-acre site was developed as a cotton mill by Craven Cotton Mills Co. It then became Dominion Textiles Co. and then Penman’s Manufacturing Co. Textile manufacturing continued on the site for almost 100 years until it was sold to a land developer in 1984. It is now being remediated for a mix of affordable housing and market-rate townhouses.
  • 180 Dalhousie St. – The 0.52-acre site is a consolidation of four properties, which, over the years, housed various residential and commercial operations, including Castelli Bakery, which closed in 2011. Today, a four-storey student apartment building is there.

Insight into the Hazardous Waste Management Industry – A Profile of Clean Harbors Facilities

by David Nguyen – Staff Writer

Clean Harbors is a hazardous waste management company operating across North America. Their location in Mississauga is a hazardous waste terminal and transfer station, receiving, handling, and transporting flammable solids destined to the U.S. for incineration. Non-flammable solids and liquid hazardous waste is sent to their facility in Lambton, Ontario. The Lambton facility includes a hazardous waste landfill and a liquid hazardous waste incinerator.

Clean Harbors coordinates hazardous waste management solutions across the Canada-U.S. border with the help of something similar to this waste management software which could help keep things in order. It is makes business sense for the company to transport flammable solids that are hazardous to its U.S. incinerator instead of having a facility in Canada. “Liquid injection incinerators are a lot cheaper,” says Mike Parker, Vice President, Canadian Environmental Compliance. “There really isn’t a strong enough market to support [hazardous solid incineration] in Canada.”

Mississauga Site Activities

Carriers bring the hazardous waste to the transfer station, where the manifests and documentation are reviewed to ensure that the facility is permitted to receive the material. Receiving times are typically planned ahead of time to prevent surges of shipments on site. Once off loaded, the waste is sampled to confirm the material profile noted in the manifest and then staged for further processing. The entire staging area is built over sealed drains leading to a blind sump to prevent any spills from leaving the site. “All the liquids from our sumps, even if it’s just rain water… get put into tanks and go down for incineration,” says Parker.

Every drum the facility receives has its contents verified, sampled, and tested. Samples are analyzed for PCBs, pH, ignitability/ flashpoint, sulfide, chloride, oxidation, cyanide, and water reactivity in order to get a profile for the waste, after which a code is attached to the drum to indicate its destination and disposal.

This information is stored in their management system that tracks the inventory at their various facilities, including the shipping information and profiles of all items. The information is removed for approval to be received on site. The system also tracks the manifests for the generator, carrier, receiver, and the ministry, internal inspections, and monthly reports to be sent to the ministry.

After sorting and sampling, the waste is safely sorted into various streams for consolidation, bulking, or blending.

“It has to be in the same waste class to mix and match. We can’t mix something flammable with something non-flammable,” says Parker.

“Even if they are in the same waste class, we take samples from each drum, mix it together, and if nothing happens, we can do it” says Erica Carabott, Facility Compliance Manager.

Liquid waste is bulked in tank farms until there is enough to fill a taker truck to be sent to Lambton for incineration. Solid waste is loaded into pits where the material is shredded up, bulked, and mixed with a solidifying agent to take up any free liquids in the solid waste streams.

Lambton Facility Activities

Many of the materials received at the Mississauga Transfer station are transported to the Clean Harbors Lambton facility offers services including waste neutralization, incineration of hazardous waste, inorganic pre-treatment of hazardous waste, thermal desorption of solid and sludge, and landfill disposal of hazardous waste.

Liquid waste is blended in a controlled neutralization process at the acid and alkali plant before being fed to the incinerator. The liquid waste injection incinerator operates 24 hours a day, 7 days a week, consisting of a fix unit incinerator, a semi-dry spray dryer absorber, and a four-compartment baghouse. The site capacity is about 100 000 tonnes per year and can process pumpable material that does not contain PCBs, pathogens, radioactives, and cylinders.

The landfill is situated in natural clay, and accepts a variety of hazardous waste excluding explosives, PCBs, radioactive, pathological wastes, or compressed gasses. Due to the Land Disposal Restriction prohibiting the disposal of untreated hazardous waste on land, Clean Harbors has an inorganic solid pre-treatment processing plant which mixes inorganic waste (primarily metal bearing solids) with reagents to prevent the metals from becoming leachable.

Furthermore, a thermal desorption unit is used to condense and recover water and organics from organic solid waste. The waste is fed into a kiln that heats the waste to 400-450 degrees Celsius to strip the organics from the waste. The vapours are condensed to remove liquid organics during the process, with the remaining emissions vented to the incinerator. The residual solids are then tested for any remaining organics or metals, and then disposed of in the hazardous landfill on site.

“You can understand why it takes a lot of money to treat the stuff in the landfill. It cooks it for about a half hour – that’s a lot of heat and a lot of money” says Parker. “With testing at the front and testing at the end,” adds Carabott .

These facilities and processes allow Clean Harbors to work with their clients to develop cost effective solutions to handling and disposing of hazardous waste materials throughout the Great Lakes Basin in both Canada and the United States. In addition, Clean Harbors conducts regular outreach programs with the local community regarding the safe operations and reporting conducted at the Lambton facility.

Contaminated Site Clean-up Opportunities in China

As reported by the South China Morning Post, China’s government recently approved a new plan to tackle growing pollution threats in its countryside, and will strive to clean up contaminated rural land and drinking water and improve waste management.

The new plan, approved “in principle” by the Ministry of Ecology and Environment is the summer also mandates cuts in fertilizer and pesticide use and improved recycling rates throughout the countryside.

China is in the fifth year of a “war on pollution” designed to reverse the damage done by decades of tremendous economic growth, but it has so far focused primarily on air quality along the industrialized eastern coast, especially around the capital Beijing.

China’s countryside has struggled to cope with land and water pollution caused not only by unsustainable farming practices, but also by poorly regulated, privately-owned mines and manufacturing plants, as well as rising volumes of plastic waste.

Rehabilitating contaminated land has become a matter of urgency for the Chinese government, which is under pressure to maximize food production while at the same time it is setting aside one-quarter of the country’s land as off-limits to development by 2020.

Total arable land declined for a fourth consecutive year in 2017 as a result of new construction and tougher environmental requirements, the government said in May.

The State Council published a plan in February to deal with growing volumes of untreated rubbish dumped in the countryside, promising to mobilise public and private funds to make “noticeable improvements” to the living environment of rural regions by 2020.

It vowed to restore wetlands, plant trees and eliminate “disorderly” rural construction to improve the appearance of China’s villages, and would also focus on improving garbage and sewage treatment.

In August, the Chinese government enacted the Soil Pollution Prevention and Control Law.  This is the first time China has enacted a law targeting soil pollution.  For existing soil pollution, the law holds polluters and users (as it is rare in China for individuals to own land) accountable for a series of risk management and remediation obligations, with the polluters being primarily responsible.

According to an article by IISD, the estimated cost for remediation efforts between 2016 and 2020 at $1.3 trillion (USD). The government itself estimates it might be able to cover only a small fraction of the overall cost.  During China’s the 12th Five-year Plan (2011–2015), only $4.5 billion) was allocated to soil remediation, mainly for urban areas.

Combine polluter payments with government support and a prohibitive capital gap still exists in China’s efforts to restore land and protect public health. This gap will have to be filled by private sources.

Can a Saskatoon brownfield be transformed into fertile green space?

The City of Saskatoon, Saskatchewan is in the process of implementing a Brownfield Renewal Strategy that it deems essential to growth in its main corridors. The initiative aims to assess and prioritize redevelopment potential of abandoned, vacant, derelict, or underutilized properties along the City’s major corridors that may have or do have perceptions of contamination.

The results of the brownfields evaluation will lead to the formulation of an incentive program that will help overcome financial and environmental barriers for redevelopment, as well as provide contamination management plans for future development.

One recent brownfield development in Saskatoon was initiated by a not-for-profit organization called CHEP Good Food.  CHEP has been promoting food security in Saskatoon for nearly 30 years. The organization is currently working toward restoring a plot of contaminated land to an agricultural plot of land.

The non-profit group, which works to promote food security, has already won a grant from CN Rail that will help them plant native trees and bushes at another brownfield site in Saskatoon and to restore the soil.   The project received the CN EcoConnexions grant through Tree Canada / Arbres Canada and Canadian National Railway Company to plant native trees and shrubs on the site.

A previous fruit and vegetable garden project by CHEP began in 2014 under a different name as rooftop gardens at the University of Saskatchewan. The project relocated to the brownfield site  in 2015 and was renamed the Askîy Project — which means “Earth” in Cree.

The latest CHEP project is more ambitious than the existing Askîy Project.  It involves growing trees and bushes directly in the soil as well as remediation the site.  A professor from the University of Saskatchewan, Susan Kaminskyj, will oversee experimental bio-remediation at the site.

The bio-remediation will consist of utilizing native a fungi that will assist the plants in growing but will also biodegrade the petroleum hydrocarbon contamination at the brownfield site.

Professor Kaminskyj explained in an interview with CBC, that the microbe is a common fungus, but one with “unique abilities.”  A property in the fungus allowed plants to grow and thrive on coarse Oil Sands tailings.  In early field trials, Professor Kaminskyj’s team found more than 90 per cent of dandelion seeds treated with the fungus sprouted on coarse tailings while no untreated seeds sprouted. The researchers also found the fungus was able to grow with diesel, crude oil and similar materials as its only nutrient source.

 

 

 

Former Contaminated Mine Site in NWT Declared Clean

The Government of Canada recently announced that the former Tundra Gold Mine, located in the Northwest Territories, has been successfully remediated.  The cost of clean-up was $110 million and was paid for by the government.

Tundra Mine was briefly operational in the 1960’s and was used as a dumping ground in the 1980’s.  It’s former owner, Royal Oak Mines went bankrupt in 1999.

Remediation of the site included revegetating soil, sealing mine openings, consolidating and isolating tailings and waste rock, treating petroleum hydrocarbon impacted soils, erecting barriers for erosion control, and removing buildings.  The clean-up project lasted more than a decade.

Though some re-vegetation has begun, the land – around 240 km north-east of Yellowknife – will remain recognizably an old industrial site for decades to come.

Dominic LeBlanc, Canada’s newly installed minister for northern affairs, called Tundra’s remediation “a great example of the hard work of northerners and the importance of partnerships with local Indigenous communities.”  Northern residents represented 76 percent of the project’s suppliers and 61 percent of its employees.  The Minister stated that the restoration will help local Dene and Métis peoples once again use the land for traditional practices.

The Canadian government will continue to oversea that monitoring of the site to ensure it remains stable.  Monitoring, using a combination of on-site equipment and drones, will cost an unspecified further sum each year.

More work to be done remediating the North

According to an article in Cabin Radio, Tundra’s successful clean-up remains a drop in the larger ocean of contaminated sites within the NWT.  Tundra is the 24th site under federal supervision to have reached this stage, a spokesperson for Crown-Indigenous Relations and Northern Affairs Canada said by email to on Cabin Radio.

federal webpage last updated in 2013 suggests Canada is responsible for more than 50 significant contaminated sites in the territory, including those 24.

separate federal website lists 1,634 contaminated sites within the Northwest Territories, where a contaminated site is defined by the Federal Goverment as “one at which substances occur at concentrations (1) above background (normally occurring) levels and pose or are likely to pose an immediate or long term hazard to human health or the environment, or (2) exceeding levels specified in policies and regulations.”

Some entries on the latter list are considered remediated and their files closed. Some are smaller sites not felt worthy of their own, separate clean-up projects.  Several dozen of them, for example, are grouped under one project to clean up the Canol Trail, a World War Two initiative which left contaminated soil, asbestos, and a range of hazardous materials strewn across 355 km of the Sahtu.

In the 2017-18 financial year, public records show federal agencies were obliged to spend money on some 275 separate contaminated sites in the Northwest Territories.  $157,000 was spent assessing a range of those sites, while a little over $103 million was spent on remediation work.

Of that figure, around $23.6 million was spent remediating the Tundra site in that financial year.

Unsurprisingly, Yellowknife’s Giant Mine – considered among the most toxic sites in Canada, harbouring 237,000 tonnes of poisonous arsenic trioxide in underground chambers – was the only site receiving more remediation money.

In the same period Canada spent just over $36 million on Giant, where full remediation work does not even begin until 2020.

Giant, like Tundra, was owned by Royal Oak when the company collapsed and the site became an unwanted federal problem. The full bill for Giant’s clean-up and maintenance – a program of indefinite, certainly decades-long duration – is expected to reach $1 billion in today’s money.

Developer takes Alberta to appeal board over former Edmonton wood treatment plant

As reported by Global News, Cherokee Canada is fighting five enforcement orders imposed by Alberta Environment and Parks (AEP) connected to the former Domtar Wood Treatment Facility located in Edmonton.  AEP has been conducting an investigation on properties associated with the former Wood Treatment Plant. As a result of the investigation, a number of Enforcement Orders were issued to the current owners, Cherokee Canada.

Nearby residents, concerned by off-site migration of wood treatment chemicals, have been kept up-to-date of the results of the AEP investigation and subsequent enforcement actions. Contaminants from a historical wood treatment processing plant continue to exist on property formerly occupied by the Domtar Wood Treatment Plant.  This contamination, which originated prior to 1987, consists of benzene, dioxins and furans, free hydrocarbons, naphthalene, polycylic aromatic hydrocarbons (PAH) mixtures, and pyrene.

AEP stated in a news release that it issued the Enforcement Orders to ensure the responsible parties implement appropriate remedial measures and mitigate the potential risks that have been identified.  The latest Enforcement Orders require that the source of the contamination be controlled and remedial measures be implemented in specific areas of the property.

Results of off-site testing for contamination in early 2018 found that contamination had not migrated off-site and that there are no health concerns in the surface soil of people’s properties. The off-site testing program was conducted by an independent third-party consulting firm under the direction of AEP.

Cherokee Canada, the developer has started turning the site of the old Wood Treatment Plant in northeast Edmonton into a new residential community but the current and ongoing legal proceedings have halted the project.  “It’s been very difficult because it’s effectively frozen our activities for three years now,” said John Dill, Cherokee Canada’s managing partner.  “It’s very expensive to go through this process, ” he added.

Houses have already been built in the neighbourhood but recently, the AEP questioned the safety of the soil.  AEP said third party testing at the site found chemicals dangerous to human health. The enforcement orders require Cherokee to remediate any contamination.

“The core aspect of these orders is to basically remove potentially large amounts of soil from these sites,” said Gilbert Van Nes, general counsel for the Environmental Appeals Board. “Domtar and Cherokee disagree that this is necessary.”

Both Cherokee Canada and Domtar have completed remediation efforts but AEP, through the enforcement orders, are claiming that they didn’t go far enough.

“Our approach was to take the contaminated soil, isolate it in a separate soil berm — again, a common practice in other jurisdictions — and ensure the soil was protected from exposure to other receptors, humans, animal,” Dill said.  “The disagreement is over how we can remediate this site so it’s safe for residential standards so that we can complete our residential development and restore the site that was previously contaminated to productive use.”

Three environmental experts are heading up the independent appeal board.  The board will pass its findings on to the environment minister and Shannon Phillips will make the final decision on whether construction can resume. However, a decision is not expected until December.
